I printed the mount from flashforge but I couldn't get it to fit all too good, maybe i bought the wrong led strip. 

So here is a simple bracket to attach basically any led bar either by glue or with bolts. Maybe a bit uglier, but hey it saves a slight amount of filament, and it has a free license.

The LED bar gets a little hot, so maybe don't use PLA.

For my setup I probably should've moved the brackets a bit further forward because a small portion of the bed isn't lit up since the light is hitting the frame, oh well.

Also if you plan on attaching using bolts, make sure they don't get in the way of things like the print head or the screen or maybe even itself.
